LEAF-RING.

Application filed April 10, 1917.

f?) all who) it may concern Be it knOWn that I, DAVID A. TRIPP, a. citizen of the United States, residing at Barberton, in the county of Summit and State of Ohio, have invented new and useful Improvements in Leaf-Rings, of which the following is a specification.

This invention relates to an improve-ll finger attachment, the same being in the nature of a ring which will be found useful to bankers, bookkeepers, and business men in general, forthe purpose of separating papers, as in turning the leaves of books, in counting money, and for a variety of purposes which will readilysuggest themselves, the purpose being to avoid the m-oistening of the finger tip with the tipof the'tongue or by the use of a moistening sponge which is more or less unclean and unsanitary.

The invention has for its object to produce a simple and eflicient finger attachment consistin in its preferred form of a ring made of rubber or of a suitable composition containing rubber, by molding said ring in proper form and providing a portion of the surface thereof, or its entire external surface if preferred, with projections or corrugations adapted forengagement with the leaves of papers that are to be handled.

A further object of the invention is to provide a simple and eflicient finger encircling ring, of elastic material, which will readily adapt itself to fingers of different sizes, said ring having a roughened paper engaging surface.

A further object of the invention is to produce a simple and elficient ring of the character described having a relatively thick portion provided with a roughened surface and a relatively thin portion which is reduced to increase the elastic properties thereof, enabling a ring of a given size to be securely fitted on fingers of various dimensions.

With these and other ends in view which will readily appear as the nature of the in vention is better understood, the same consists in the improved construction and novel. arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claim.

In the accompanying drawing has been illustrated a simple and preferred formof the invention, it being, however, understood Specification of Letters Patent.

Serial No. 161,070.

that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of'the claim may be resorted to when desired.

In the drawing,

Figure l is a plan view showing a simple and preferred form of the invention.

Fig. 2 is a side elevation of the same.

Fig. 3 is a. transverse sectional view taken on the line 33 in Fig. 1.

Fig. 4 is a side view of a ring of a somewhat difierent design.

Fig. 5 is a plan view illustrating a modified form of the invention.

Fig. 6 is a side view of the same.

Fig. 7 is a plan view illustrating a further modification.

Fig. 8 is a side View of the same.

Fig. 9 is a plan view illustrating another modification.

Fig. 10 is a side view of the same.

Figs. 11. and 12 are plan and side views illustrating a further modification.

Corresponding parts in the several figures are denoted by like characters of reference.

The material of which the improveddevice is preferably made is rubber or a composition containing rubber, no claim be ing herein made to any precise composition or to'any particularmode or manner of manufacture, it being understood that any well known manner of manufacture may be resorted to.

The, device in its preferred form consists of a ring or annulus having a relatively thick portion 15 and a relatively thin portion 16, the body of the ring being gradually tapered from the thick to the thin portion. The thick portion has been shown as being equipped with a specially reinforced por tion 17 of relatively great thickness throughout, said reinforced-portion resembling in its general appearance the setting of an or namental finger ring. The face of the reinforced portion 17 is roughened or corrugated as seen at 18 in Fig. 2 by transversely intersecting grooves or channels.

In Figs. 1 and 2-the reinforced portion 17 has been shown as being of substantially square formation. In Fig. 4: has been shown a diflerent design whereby the reinforced portion is made of rhomboidal shape, and

only a portion of the surface of said reinforced portion has been grooved or corrugated.

In Figs. 5 and 6 the reinforced portion 17 is omitted, and the external surface of the relatively thick portion only has been shown as being roughened, in this instance by means of parallel grooves or channels only as indicated at 19.

Under the construction shown in Figs. 7 and 8 the relatively thick portion of the ring or annulus has been shown as being provided with a plurality of reinforced p01- tion here designated by 20, the external surface of each of said reinforced portions being provided with minute nipples or projections 21 which constitute the roughened paper engaging portion of the device.

By the construction shown in Figs. 9 and 10 the relatively thin portion 16 of the ring or annulus is further weakened by providing the edges thereof with one or more notches 22, the purpose being to still further increase the elasticity and resiliency whereby the ring will adapt itself t various sized fingers.

In Figs. 11 and 12 a still further modified construction of the invention has been illustrated. By this construction the ring here designated by 16 has been made of equal thickness throughout and its entire outer and inner surfaces have been provided with corrugations, here designated by 21 and 21 respectively. When the ring is made in this shape any portion of the circumference thereof may be utilized as a paper engaging surface, and the ring does not therefore require to be turned to an exact predetermined position prior to the use thereof. The corrugations 21* on the inner face of the ring will also serve to snugly engage the finger of the operator and to prevent the ring from turning to an undesirable position. It is obvious that the corrugations may be applied to the inner face of any of the difierent forms of rings herein described. It will likewise be obvious that the ring having its outer and inner surfaces corrugated as seen in Figs. 11 and 12 may be weakened at any point of its circumferenceto facilitate its adjustment on the finger of the operator, in the'manner heretofore described and applied to several forms of the improved ring.

The device while not in active use may be worn after the manner of an ordinary ornamental finger ring, and the parts thereof may be rendered ornamental by variously coloring the same or in any other manner. that may suggest itself. While in active use the device may be worn on the thumb or on any one of the fingers or on both thumb and one or more fingers, the thickened paper engaging portion being usually. turned inward in a manner Which will be readily understood, it being, however, also understood that no limitation whatever is made or intended to any particular manner of wearing or applying the device for use. It is also to be particularly understood that while several modified forms of the inven tion have been herein shown, the construction may be further modified to almost unlimited extent without departing from the spirit of the invention.

Having thus described the invention, what is claimed as new is:

A leaf ring of uniform width and with a roughened portion, said ring being of maximum thickness at and throughout such roughened portion and gradually reduced in both directions therefrom to a point dia-, metrically opposite such thickened portion to provide a portion of minimum thickness, the width of the ring being reduced by transversely-opposed notches at such point of minimum thickness. 1

In testimony whereof I aflix my signature. DAVID A. TRIPP.
